| 摘 要： | 甘肃大滩钛铁矿田是岩浆溶离型单一钛铁矿矿床，以其物质组分简单、规模巨大、品住低为其特点，经过四次选矿实验研究，证明该矿石为易选矿石，采用磁选-浮选工艺流程，回收率可达75．12％，品住(TiO2)48．22%；通过对矿石物质组分及矿物赋存状态研究，为该矿床的可开发利用提供了依据。 |
| 关 键 词： | 钛铁矿床 岩浆熔离 矿物组分 赋存状态 |

| Abstract: | An ilmenite deposit in Datan of Gansu Province, with characteristics of simple component, huge scale and low grade, is a magma liquation deposit. Four times of dressing tests prove that the useful part of the ore is easy to be separated. Using magnetic\|flotation separation process, the recovery rate can be up to 75.12% and the concentrate grade (of TiO\-2) reaches 48.22%. The research on the ore component and mineral occurrence state of the deposit will provide a basis for its development and utilization. |
| Keywords: | ilmenite deposit magma liquation ore component mineral occurrence state |
